l Application Ied January 26, 19215. Serial No. 4,925'.

j My invention relates to a system for forming concrete foundations and walls for buildin-gs.

The `object Voi the invention is to provide a system of this kind in which the wall may be formed oi large slabs provided with means for iirmly holding the same in operative relation to each other, and mounted on 'a foundation adaptedl to drain away any water that Vmight percolate through the slab and make` its way into the cellar oi the building. Y

Another object is kto provide for a construction which, while being thoroughly good, will yetiloe comparatively cheap, and will permit A`of the very rapid erection of the 'building with which it is employed.

Minor 'objects will appear in the subjoined description. Y

The invention consists in the novel construction of the `'part-s, zand their arrangement relatively to each other when they are assembled, as will'b'e hereinafter described and claimed, reference being had to the accompanying drawings, in which Fig. l isa horizontal section oi a portion off a* wall formedy in accordance with my invention.

l Fig. 2 is a perspective view of one form of 'the building slabs used.

Fig. 3 is a plan view of the inner side of one of these slabs, with its reinforcements shown in dotted lines.

Fig. 4 is a perspective view, on an enlarged scale, oi the angleclamp which forms animp'ortant part of my invention; and,

j Fig.` 5 is a sectional view showing the method oi mounting the slabs on the foundation in the formation of a wall.

The numeral 1 indicates a slab used in the formation of the walls of the building. This slab is preferably recessed or 'chan-V neled longitudinally on its inner side, thereby providing it at opposite sides with the vflange 2, in which are formed the semicircular recesses 3, which latter open at their vouter ends into'recesses t on the outer face oi the slabs, and these recesses arearian'ged to register with the recesses in other slabs when the slabs are placed in position in the wall, so that the semi-circular recesses 3 whenthey register lwith'each other Yin adjacent slabs nform cylindrical openings `be'ti've'en the slabs. The registering iace 'recesses e onad-jaeent blocks have their bottoni portions formed in planes inclined at right Vangles to each other, as clearly shown in Fig. l. The slabs l are also provided on their inner channeled sides with studs or projections 5 which terminate in the same plane with the inner edges of the side 'flanges 2, and are provided with central openings 5a which extend outwardly through the slab and open at their outer ends intogthe face recesses 6 (see F l) which are the same sized recesses as those formed at the meeting sides of adjacent blocks by the registering recessesri.

Special attention is called to the angle clamp 7, consisting of the middle portion 7a and the end portions 7b; disposed at right angles to each other,l or t5 degrees to the middle section. Each clamp is provided with a centralv bore 8, for the reception ot a suitable bolt 9, as shown in Fig. l.

The foundation ot the building is provided o'n its topy side with a ,longitudinal recess 10 of la width to receive the slabs lon edge therein, and in the bottom of this recess extending downwardly and outwardly from the inner side thereof are a series of recesses il opening at the outer side oi' the foundation into a ditch 12. which surrounds the foundation, and is filled with gravel.

In operation, the slabs are set up opposite each other, oneslab to form the inner wall, and the other the outer wall; or the outer slab only may be used, in which case it may be attached to any supporting frame or structure, for the purpose oi' forming a building wall.

It is when used as a basement wall or as a wall for the first floor above the foundation for a dwelling or small structure, that the groove or recess 10 is employed.

In erecting a building, it is best to begin at one corner, setting up the special corner post 14 (which is also provided in its edge and faces with the recesses 3 and 4 respectively just as are the slabs l), and attaching thereto a regular slab l, (also indicated by F in the drawings to distinguish it from other similar slabs in the wall shown in Fig. l) and a lhalf-section slab E, all with the bolts 9 and the clamps 7, It will be seen that the inclined ends 7l of the clamps -fit the inclined bottoms of the re cesses 4, Vin such a way `as to simultaneously bind the slabs -Eandffl1 tothe corner-post to each-other. When theslabs E and.

F are attached to the corner post 14, then a tach the halt and full section slabs A and C respectively, at right angles to the first slabs attached. From these tivo starting points, full sized slabs are attached on both inner and outer i-'aces until the nent corner is reached where it is again necessary to place a halt section on one tace to even up the inner and outer Walls Where connecting with the corner post as it is reached.

The importance ot the angle-clamp T becomes apparent, -when it is considered that it makes it possible With a single bolt to dran' the inner and outer slabs together, ivhile at the same time bringing the abut ting ends ot the adjacent slabs also firmly together.

The reinforcements lf3 are important, as they give the required strength at the points u'here the clamp pressure comes.

The edges and inside faces ot the stabs may be coated ith a moisture-prooiP material such as asphaltum, Whenever deemed necessary.

rl`he slabs may be made quite large, but Whenever it is necessary to have more than one slab in height, the slab is provided at its ends with flanges the same as the flanges :2 at its sides, and these additional 1danges also have semidioles and counterbores just the same as in the side flanges; and the joints are staggered horizontally as Well as vertically.

Special sizes and shapes ot slabs may be necessary ivhere Windenv and door frames come; but in any event, the same method of connecting the parts together is employed.

The projections 5, on the inner faces of opposing slabs abut the iianges on the oppositeA ivall. and thus strengthen the slabs at their centres, ivhile the channeling or recessing ot' the slabs on their inner sides terms air spaces betiveen the inner and outer ivalls, and thus lightens the Wall, while at the same time making itI a tine non-coiuluctor.

Having noiv described my invention, ivhat l claim as new and desire to secure by Letters Patent is:--

l. In devices of t-he character described, the combination in a Wall. ot opposing building slabs provided in their meeting edges with transverse recesses tern'iinating at their outer ends in larger recesses in the faces ot the slabs, the recesses in the edge ot a slab being arranged to register ivith those in the edge ot the adjacent slab, and being complementary thereto. the bottoms of the tiro parts or" each complementary recess in the slab 'faces being arranged at an angle tacing outwardly from each other; a clampplate for each complement-ary face-recess, said plate having its ends disposed at an angle to engage said angular bottoni parts ot' the recess; and bolts passing through said transverse recesses into said face-recesses and adapted to press said clamps into binding engagement vvith said angular recess bottoms, to dravv each other the tivo slabs containing a complementary recess.

bolts passing through the registering transe verse recesses of opposing slabs to dran' said slabs tovvard each other, said bolts being also adapted at the same time to press the clamps into binding engagement with said angular bottoms; whereby the bolts not only bind the opposing slabs together but also simultaneously therewith press the meeting edges of adjoining slabs into abutting engagement with each other.
